Hi i have an 1989 525i and ive noticed sometimes when its cold the dash board dials will flicker randomly. I presume this is the capacitor problem and hasnt really bothered me as it works after a while.
Recently though ive noticed that the brake hydraulic light sometimes wont come on (as well as the dials flickering) and the car just wont start. Could the car not starting really be affected by the dashboard or is it just a coincidence?

Thanks for any replies.
